APPARATUS FOR SEALING PAPER CONTAINERS Application filed April 10,

This invention relates to apparatus for forming containers,.especially those made of paper or similar material, that are substan tially tubular or conical, with a bottom at one end, and when filled with a liquid, or other material, are sealed by pressing together or collapsing the opposite edges at the upper open end; and then a bent strip of metal, or other material, is sometimes applied to seal the meeting edges and form a closure for the container.

This operation is sometimes carried out in a filling and sealing machine, in which the containers will intermittently advance, and first travel below a filling mechanism or tank where they receive the contents and as the containers are advanced by the conveyer, they are collapsed, and at a further station in the machine are sealed. I

These containers are sometimes constructed of a body in the form of a rolled blank in which the meeting edges are secured together, and form an upright seam in the container, and thus provide a kind of ledge on the outer face of the body.

In the sealing machinethe collapsing'and sealing operations are sometimes produced by opposed jaws or clamping members, that are brought together against the container top portion, and other jaws served tosecure a sealing strip; and these two operations are sometimes effected in a vertical plane that is transverse to the plane of advance of the conveyers. Since the containers are usually provided withprinted matter,it is an object to collapse and seal the container so that the printed matter will appear on one of the comparatively fiat sides or faces of the sealed container, andals o the upright seam of the body is preferably arranged on the opposite side of the sealed container from the said printed matter; Therefore it becomes necessary to so apply ,or position the containers on the conveyer,that when sealed the printed matter and the seam will always have the same relative position to the said fiat face, and, it is an object of this invention to provide means for the proper positioning of the containeron the conveyers. a

Q right seam 5 of the body member, are placed 1929. Serial in. 354,067.

In the accompanying drawings showing one embodiment of my invention:

Fig. 1 is a plan view of the conveyer show ing three of the seats for the containers.

Fig. 2 is a side elevation of the parts shown in Fig. 1.

Fig. 8 is a plan view and Fig. 4; a front elevation of a portion of a filling and sealing machine.

Fig. 5 shows the containers on the chain seat before sealing; and Fig. 6 shows the same after being collapsed.

As shown in the drawings the receptacles 6 are of conical form, comprising a body 7 and a bottom 8, in'the form of a flanged disc with the margin of the body and disc rolled inwardly in the form of a bead. These containers are usually advanced on a conveyer, and in the form shown, the containers are carried on seat members 9, carried by an endless chain 10, that is intermittently advanced to bring the containers to a filling machine, and then to a collapsing member, and on further advance to a sealing member.

In Figs. 8 and 4, a machine of this kind is indicated in which the chain 10 is carried by Sprockets 11 and 12, whereby the containers on the seats 9 are brought to a filling machine, denoted generally by 13, then advanced to a collapsing machine 14, and on further advance are engaged by the sealing mechanism 15. The collapsing is done by jaws 16 and 17 that are brought together on a vertical plane transverse to the path of the chain. The securing of the sealing strip is done by similar pair of jaws 18 and 19, that are also brought together on a vertical plane transverse to the path of the conveyer, as shown in Figsf3 and 4. The containers having the upon the seats 9 so that this seam, will be in the medium line of the path on the conveyer, and

preferably at the rear, in the direction of travel, as indicated by the arrow; it being understood that the printed matter on the con- 3 tainer body is on the side opposite to this seam. Each of the seats 9 is provided with a stop member that will engage the edge of this seam when placed on the seat, and as shown a bracket 20 is mounted on each seat, TM

with a stop arm 21 projecting therefrom. On the opposite side of each seat is mounted an arm 22 carried by a bracket 23, and this arm that may be resilient, will serve to press the container against the bracket 20 at the bead portion 8, while. suitable stop pins 24, 25 on the seat at the rear, will properly position the container. The stop 21 andthe arm 23 are preferably arranged to engage the body at the upper portion ofthe bead 8 and'will tend to hold the container on the seat and prevent tipping thereof. 7: It will be see'n 'thati" the stop 21 will engage the seame of the con-: tainer when it is applied by sliding it from the seam will be in the middle of one flat edge at the top, and the printed matter on the opposite side. The arm 21, and also the arm 22 will engage the top of the bead of thebottom member and retain the containers on the seats.

What I claim is c c 1. In a machine for collapsing and sealing paper containers that have a side seam, the

V combination with the collapsing and sealing mechanism, and a carrier provided with a series of seat portions for the containers and Which carrier is advancedto bring the containers on the seats to said collapsing-and sealing mechanisms, of a stop guide arranged to engage the contalner side seam when placed on the'carrier seat, whereby the,jsiole' seam of the container will always lie in a certain predetermined fixed position relative to the line otseal onthe container top as sealed bylthe 'machine. 2
